A distribution of values is normal with a mean of 200 and a standard deviation of 15. From this distribution, you are drawing samples of size 18. Find the interval containing the middle-most 70% of sample means:

What is the name used to describe a graph where for some value of x, there exists 2 or more different values of y?

F(x) = x2 − 9, and g(x) = x − 3 f(x) = x2 − 4x + 3, and g(x) = x − 3 f(x) = x2 + 4x − 5, and g(x) = x − 1 f(x) = x2 − 16, and g(x) = x − 4 h(x) = x + 5 arrowright h(x) = x + 3 arrowright h(x) = x + 4 arrowright h(x) = x − 1 arrowright

What value is a discontinuity of x squared plus 8 x plus 4, all over x squared minus x minus 6?
